I'm a newer reloader and am having good success with 9x19 Luger. I also shoot 9x18mm Makarov. I see that Mak dies exist -- is that necessary or can I just use my existing 9mm dies and adjust them for the shorter Makarov cartridges?

I'm also wondering if it would be useful to have a dedicated setup (one for Luger and one for Makarov). What are the forum's thoughts?
